WINDOW-CURTAIN STRETCHER.

Application led September 24, 1918.

To all whom it may concern:

' Be it known that I, CHARLES LATHAM, a

citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Window-Curtain the following is a speciiication.

This invention is a window curtain stretcher and has for its principal object the production of a frame so constructed as to stretch the -curtains after the same has been washed or to retain curtains in a stretched condition when in use in conneccausing the curtains to at all times, and thus present a pleasing appearance.

Another object of this invention is the production of a curtain stretcher or support which consists of a frame of an adjustable nature, thus allowing the device to be used in connection with curtains and windows o various sizes.

Another object of this invention is 'the production of a window curtain stretcher wherein a plurality of telescopic tubes are provided and are connected together to form a rectangular frame of an adjustable nature.

One practical form of .construction and assembly ofthe present invention will be hereinafter described 'and isv illustrated in the drawing, in which- Figure 1 is a front elevation of the window curtain stretcher.,

Fig. 2 is a side elevation ofthe device.

Fig. 3 is an enlarged sectional view of the device taken on the line'33 of Fig. 1.

Fig. 4 is a longitudinal section through the telescoping tubes illustrating the manneigl in which the same engage each other, an

Fig. 5 is a fragmentary sectional view illustrating the connection between one of the uprights and one of the horizontal tubes of the device.

In the preferred embodiment of the present invention about to be described, it will be seen that 10 designatesV a window frame, upon which the device is to be carried when used for supporting curtains in a stretched condition to prevent the same from wrinkling and also to cause the curtains to present a pleasing appearance, although it is obvious the frame may be employed for stretching the curtains after the same are washed.

v The horizontal supporting members cornprise primary tubes 11 and auxiliary tubes 12, the tubes 12 telescoping within the primary tubes 11. The tubes 11 are provided with 'clamping bands13 adjacent their ends, thus holding the ,tubes 12 by frictional engagement against tendency of accidental slipping when in use. The tubes 11 and 12 are provided with ends 14 bent to extend at right angles thereto and having clamping rings 15 engaging the sleeves 16 extending into the ends 14 and carrving wall plates 17. Thus it will'be seen that the wall plates 17 may be fixed upon a Window frame 10 and retain the major portions of thev horizontal supporting members spaced from the window frame. y

In order to reinforce the horizontal supporting members intermediate their ends brackets 18 are connected to ,the window set position as illustrated in Figs. 1 and Vertical uprights consist of kprimary tubes 2() land auxiliary tubes 21, the tubes 21 19 for beartelescoping within the tubes 2 0'. The primary tubes l2O are provided with clamping bands 22at their upper ends for causing the ends of the primary tubes 20 to firmly bind upon the tubes 21 for holding the same against accidental shifting. The tubes -20 and 21 are provided with blocks 23 attheir outerl ends and` threaded stems 24 extend from-the blocks 23. These stems 24 are `pressed through the tubes 11 and 12 of the horizontal supporting members, adjacent the ment illustrated in Figs. 1 and 2. The knobs 25 havinggnuts 26 are screwed on to the stems 24, since these stems extend through and beyond the tubes 11 and 12, thus holding the uprights in fixed engagement with the horizontal supporting members.

When the device is in use for supporting curtains contiguous to a window frame, the tubes 11 and 12 are slipped into suitable receiving portions at the ends of the curtain, in thel usual manner. The tubes are then telescoped and thus a substantially rectangular frame is provided, in view of the fact that tubes 20 and 21, constituting the uprights are atthis time connected to the tubes 11 and 12. The wall plates 17 may then'be moved in desired directions to eX- pand the tubes 11 and 12, thus spacing the the -manner illusuprights at a greater distance apart, while the horizontal supporting members mayv be moved away from each other, thus increasing the length of the uprights by retracti-n A the tubes 2l from the tubes 20. The wall plates may then be fixed upon the window frame and the curtains held in a taut condition. Conversely, if it is desired,the tubes 21 may be moved into the tubes 2O and the tubes l2 into the tubes ll, thus reducing the size of the frame. Under any condition, however, regardless of the movement of the tubes it will be seen ythat when the uprights are connected to the horizontal supporting members the frame will be of a rectangular construction, and may be adjusted to present a device of various sizes desired'.

The foregoing description and the drawings have reference to what may be considered the preferred, or approved form of my invention. It is tov be understood that I may make such changes in construction and arrangement and combination of parts, materials, dimensions, et cetera, as may prove expedient and fall withiny the scope of the appended claims.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is z* l. A device of the class describedcomprising two parallel tubes, eachhaving each end bent at right angles to its body, fastening devices in eachextremity thereof, two other parallel tubes having blocks in their extremities, threaded stems projecting from said blocks beyond the ends of-these tubes and adapte-d to bev passedV through the other tubes, and knobs screwed onto saidY stems where they protrude.V
